"If there is a one-minute span that best sums up what's gone on with the Thunder in the first five days of their Western Conference title defense, it began with 2:30 to play in the fourth quarter at home on Sunday against the Hawks, who were shorthanded without star forward Josh Smith. Atlanta was up, 95-91, and the ball went to center Zaza Pachulia in the high post, guarded by Kendrick Perkins. Guard Lou Williams, who had been chewing up the Oklahoma City defense in the quarter with 10 points, was coming off an Al Horford baseline screen on the low left block. Horford's man, Serge Ibaka, was eager to keep the ball out of Williams hands, and lost track of Horford, who rolled toward the rim. Pachulia found him in the paint, and Horford had an easy dunk.
